FLOOR-PROTECTORS FOR STOVES.

UNITED STATES PATENT OFFICE,

FREDERICK J. SEYMOUR, OF WOLCOTTVILLE, CONNECTICUT.

IMPROVEMENT IN FLOOR-PROTECTORS FOR STOVES.

Specification forming part of Letters Patent No. 186,063, dated January9, 1877 application filed October 31, 1876.

To all whom it may concern Be it known that I, FREDERICK J. SEY- MOUR,of Wolcottville, in the county of Litchfield and State of Connecticut,have invented an Improvement in Floor-Protectors for Stoves, &c., ofwhich the following is a specification:

This invention relates to the peculiarity of the rib surrounding theplate of zinc or other metal forming the floor-protector.

The object of the invention is to make a heavy and strong rib out ofcomparatively thin sheet metal, so that the rib will not be bent orbecome out of shape by the use to which the same is put, and at the sametime the floor-plate can be easily cleaned from the ashes and similarmaterial often falling upon the same.

This invention is an improvement upon that for which Letters Patent weregranted to me October 24, 1876.

In the drawing, Figure 1 is a section of the rib at the edge of thefloor-plate, and Fig. 2 is a plan of a part of the edge.

The floor-plate is circular, elliptical, or of other desired shape, andthe edge is formed into a head or rib by rolling up the sheet metal bydies or by a spinning operation, so that there are two thicknesses ofthe sheet metal in the upper and outer portions of the rib, as set forthin my aforesaid Letters Patent.

My present invention relates to the double fold made in the sheet metalat the portion a of the rib between the rib b and the plain surface 0 ofthe sheet metal forming the floor-proteotor.

This double fold a is bent up in the act of embossing the sheet metal ofthe rib, and results from the embossing roller or tool flattening thecylindrical rib to lessen its height, and at the same time carrying downa double fold of the metal between the rib and the fiat portion of theplate 0. This fold tends to produce a tension upon the fiat sheet metal,and thereby cause the said plate to lie flat, and at the same time anincline is formed to the inner edge of the rib to facilitate the removalof ashes, dust, &c., over the edge of the floorplate, because there isnot a groove at this portion of the plate, which groove would exist wereit not for the double fold aforesaid.

I claim as my invention- The floor-plate, having a rib of sheet metalaround its edge and a double fold at a in the metal, for the purposesand substantially as set forth.

Signed by me this 26th day of October, A. D. 1876.
